I

2、f I were you , I would go to tell him the real feeling upon him. If I were a boy, I would join the army. If the had time, she should go with you. 2. 表示與過去事實相反If he had taken your advice , he wouldnt have made such a bad mistake. She would have come to enjoy the party if she hadnt been very busy. If

If he were to be given another chance to do it again, he could certainly achieve more. If it were to rain tomorrow, the football match would be put

4、 off. 1. 虛擬條件句的倒裝在虛擬條件句中,為了強調(diào)所假設(shè)條件的虛擬性,或突出說話人的一種主觀愿望,虛擬條件句可用倒裝結(jié)構(gòu)； 有時侯在使用時可省略if, 把條件從句謂語中的助動詞、情態(tài)動詞或系動詞放在句首實現(xiàn)的,句子就可換成以下形式,即“ were / had / should + 主語 ”；如：Had I been= If I had been in that situation with so much money. Should there be = If there should be a droughtWere I a boy, I would join the army. ,

5、 I would not have let the thief escape away , what should we do at that time . Had he taken my advice, he would have succeeded. Were it not for the expense, I would go to Britain. 2. 錯綜時間條件句有時條件從句的動作和主句的動作發(fā)生的時間并不一樣,這時謂語動詞的形式應(yīng)依據(jù)它所要表示的具 體時間來準備；例如：If we hadnt been working hard in the past few years smo

6、othly. If the Party hadn t led the Chinese people to liberate the country still live a life in pain and poverty. 3. 含蓄條件句, things wouldnt be going so , Chinese people would 有時假設(shè)的情形并不以條件從句的形式表現(xiàn)出來,而是通過某個介詞或介詞短語 如： with ,otherwise, without, but for, in that position 、上下文或其它方式表現(xiàn)出來；這種句子稱為含蓄條件句；例如：第 2 頁,共
